Resource Mapping and Monitoring

Wildlife movement and distribution can be influenced by local conditions like topography and landscape features, and the distances within which species respond to their landscape – scales of effect – can vary over space and time. We are estimating scales of effect for wildlife population trends to help land managers determine the distance within which wildlife will respond to landscape change.

Invasive grasses are degrading sagebrush in western states. Can sheep help us restore these ecosystems?

Posters covered a wide range of topics as local graduate students and EROS scientists shared their work in the EROS atrium.

LANDFIRE is a diverse product suite with countless uses that go beyond fire management. The program has now been providing this satellite data for 20 years.

What can you learn during an internship at the USGS EROS Center? A lot! Several interns talk about their experience working a summer internship at EROS.

Eyes on Earth is a podcast on remote sensing, Earth observation, land change and science, brought to you by the USGS Earth Resources Observation and Science (EROS) Center. In this episode, we learn what satellites can tell us about mangrove forests.

The USGS Land Change Monitoring, Assessment, and Projection initiative aims to identify where the landscape is changing and why.

Many factors determine how human beings modify the earth's landscape. Land-cover change is inherently a local event, yet broader scale socioeconomic and biophysical factors also affect how humans make decisions to use the landscape. Projecting future land cover requires modelers to account for driving forces of land-cover change operating at scales from local ("bottom-up") to global ("top-down")...

Evapotranspiration (ET) rates – the combination of evaporation from soil and transpiration from plants – are powerful tools in the management of scarce water resources. Taken alone, however, those rates leave unanswered questions about water sources, questions that can offer guidance and insight on challenging decisions in areas reliant on irrigation. Researchers at EROS work to offer that insight...

A planet with a changing climate and growing population forces tough decisions about the use of limited resources. Making sustainable choices in the face of global change requires an accurate cataloging of those resources. Since 1991, EROS has been the North American node for the United Nations Environment Programme’s Global Resource Information Database (UNEP-GRID), which tracks environmental...

Satellite data archived at EROS serves a critical role in the assessment of food security for FEWS NET – the Famine Early Warning System Network.

A planet with limited water resources needs accurate, reliable and frequently-updated tools to measure water use and plan for future needs. Scientists at EROS harness the remote sensing capabilities of satellite data to offer powerful tools that resource managers across the United States can use to gain insight into the water use needs of agricultural land, forests, and public green spaces.
